-## NFC library for Arduino
-
-This is an Arduino library for PN532 to use NFC technology. It's based on 
-[Adafruit_NFCShield_I2C](http://goo.gl/pk3FdB)
-and improved by [Seeed Studio](http://goo.gl/zh1iQh).
-It works with:
-
-+ [Elechouse NFC Module](http://goo.gl/i0EQgd)
-+ [NFC Shield](http://goo.gl/Cac2OH)
-+ [Xadow NFC](http://goo.gl/qBZMt0)
-+ [PN532 NFC/RFID controller breakout board](http://goo.gl/tby9Sw)
-
-### Features
-+ Support I2C, SPI and HSU of PN532
-+ Read/write Mifare Classic Card
-+ Works with [Don's NDEF Library](http://goo.gl/jDjsXl)
-+ Support Peer to Peer communication(exchange data with android 4.0+)
-+ Support [mbed platform](http://goo.gl/kGPovZ)
-
-### Getting Started
-1. Download [zip file](http://goo.gl/F6beRM) and 
-extract the 4 folders(PN532, PN532_SPI, PN532_I2C and PN532_HSU) into Arduino's libraries.
-2. Downlaod [Don's NDEF library](http://goo.gl/ewxeAe) and extract it intro Arduino's libraries.
-3. Follow the examples of the two libraries.

-### To do
-+ Card emulation
